Educational context only, not a diagnosis or clinical assessment. Product-authored items are labeled where validated instruments do not apply.
§ 01 — Findings
What the study found
- The active MindSync core and inactive extended bank are separate product layers; a larger bank does not by itself establish predictive validity.
- Question ids preserve facet and domain namespaces so aggregation and confidence reporting remain inspectable rather than falling back to a coarse trait bucket.
- Public interpretation stays at the level of starting hypotheses, shared ground, possible friction, and uncertainty; it does not claim to predict relationship outcomes.
§ 02 — Encoding
How we encode it
- Explains why PsiMatch exposes confidence and stability alongside compatibility interpretation.
- Documents the boundary between research-informed item domains and product-authored questions.
